STOVE Filed Feb. ,28, 1951 l:s `sheets-sheet s Patented-May 31, 1938UNITED STATES PATENT OFFICE STOVE Bertrand B. Kahn, Cincinnati, Ohio,assignor to The Estate Stove Company, Hamilton, Ohio, a

corporation of Ohio One of the principal objects of the invention is toprovide an improved construction in a stove for facilitating thehandling of the foodstuffs;l

and permitting of suitably inspecting, positioning and handling of thefoodstuffs even while the oven is being heated.

Another object of the invention is to provide an oven arrangementcomprising a slidable drawer containing a food supporting member, andmeans for adjusting the food supporting member vertically independentlyof the drawer sliding mechanism.

. Other objects and advantages of the invention will be apparent fromthe description` thereof set out below and from the accompanyingdrawings and the appended claims.

In the drawings, which -illustrate.a preferred embodiment of theinvention, asv incorporated in a stove, the main body of the stove isdesignated by the numeral III, one of the several supporting legs ofwhich is shown at II.. The main body of the stove and the remainingfeatures thereof need not be shown to afford a complete disclosure 'ofthis invention and therefore only a small fragment'oi the stove bodysurrounding a single oven, is shown. The legs II are conveniently madeadjustable in height so that the stove may be positioned at just theright height for the individual operator. Suitable heat insulatingmaterial is provided for exposed oven walls, as indicated by the numeralI2, such material being of any suitable, known character.

The oven is provided with a slidable and preferably removable drawermember which carries mechanism for supporting the broiler pan or tray 5in vertically adjustable relationship within the drawer member. Thisdrawer member comprises a front member forming a closure for thecompartment when the'drawer is in closed position, and having spacedwalls I5 and I6, between 10 which is heat insulating material, and whichforms a closure for the broiler compartment when the drawer member isclosed.

A metal plate I8 is bolted by suitable bolts I9 to the end wall I6 andspaced therefrom a su- 15 cient distance to form a compartment housingthe pan elevating mechanism, the sides and top of the plate being bentat right angles to its face so that the mechanism is completelyenclosed. The inner end of the drawer is formed by bolt- 20 ing togethertwo bent sheets of metal 20 and 2|, the former also being provided withright angularli7 bent side and top portions so that between them theyform anenclosed compartment for the pan elevating mechanismI at this endof the 25 drawer.

The sides of the drawer are shallow and are formed of metal strips 22which are bent outwardly at their upper edge to form a ange 23 and arebent inwardly at the lower edge 24 to 30 form a supporting portion. Theplate, I8 is y formed with right angularly bent projections 25 at itslower portion which are attached to the y support 24 in a convenientmanner such as by welding. Likewise the metal sheets' 20 and 2| 35forming the inner end wall of the drawer are made with right angularlybent projections 26 and 21 which are also welded to the support 24.'

- Rollers 28 are mounted on the vertical portion of the strips 22 at theinner end thereof and 40 form the support for the inner end of thedrawer member.

A track member is mounted within the oven' compartment, this track beingshown 'as a strip of metal 30 having a bent over flange 3l which 45 isattached to the interior wall of the broiler compartment by suitablemeans, such as rivets p 32, the body portion being thus spacedtherefrom. a short distance. This metal stripextends along thecompartment wall from the front to 59 back and the lower portion is bentto form a horizontally extending portion 33 which serves as a track uponwhich the rollers 28 supporting the rear end of the drawer ride. Beyondthe track portion. 'the strip is again bent downward- 55 ly at 34 forattachment to the stove framework.

A roller 36 is mounted upon the vertical body portion of strip 30 andsimilarly another roller 31 is also mounted upon this strip butpositioned closer to the front of the oven. These two rollers are indifferent horizontal planes and so spaced that there is guidingclearance between them for the ange 23 of the drawer. The flange 23 thusserves as both guiding and supporting means for the drawer as it ismoved into and out of the broiler compartment. This flange is alsoprovided with an upturned portion 42 at the extreme inner end of thedrawer which serves as a. stop when it engages the roller 36 in theforl5 ward position of the drawer. This represents the normal movementofthe drawer and when in this position, the pan is practically clear ofthe oven so that it may be readily removed. It will be noted that theside walls of the drawer are 420 quite shallow and that the pan, even inits lowermost position, is supported above the side wall andconsequently may be easily. grasped at the sides and removed.

^ When it is desired to withdraw the drawer farther, the front endtilted-upwardly to cause the stop member 42 to be depressed and to clearthe lower surface of roll 36 and then the drawer may be withdrawn sothat the pan will entirely clear the oven compartment. 'I'he rollers 31and 28 are of such size and are so positioned that the roller 28 willnotpass under the roller 31. Consequently there is no danger, even when thedrawer has been removed to its extreme outward position, of having thesame fall out of the oven unexpectedly. To completely remove the drawer,the inner end `thereof is raised so that the roller 28 may be moved overthe roller 31, and the entire drawer may be withdrawn completely.Mounted in the front member of the drawer is a shaft 52 adapted to berotated in suitable bearings 54 and 55 which are formed in the plates I6and I8 respectively by punching the same and bending over the edges ofthe material to form a bearing surface. A pinion 5I is xed to shaft 52detent 56 which is mounted upon the bent over top surface of the sheetI8. This detent yielding- 1y engages the teeth of the pinion and servesto hold the same in any position in which it is left. A large segmentalgear 58 is rotatably mounted upon a shaft 59, which is carried insimilarly formed bearings in both front and rear walls I8 and 20 of thedrawer, and which extends the entire distance between these two walls.The teeth of this gear are adapted to engage the pinion 5|. Projections60 are formed at each end of gear 58 to serve as stop members when theyabut against the pinion .55 in either extreme position of the gear.

A lever 6I is xed to the shaft 59 within the compartment formed byplates I6 and I8, and is pivoted at one end to two operating links 62,one of these links being placed upon each side of the lever and spacedapart a predetermined distance. The links 62 in turn are pivoted to oneof a pair of pan supporting arms 63, 64, which in turn are pivoted at65, 66 to the plate I8. In order that the pivot points shall not extendinto the oven or interfere with the removal of the pan, depressions 61,68 are formed in plate I8 of such a depth that the pivots are indentedfrom the surface of the plate I8. The arms 63 and 64 are formed withintermeshing gear teeth 69, 10 at their adjacent ends and thus it isinsured that the two arms will move in unison, for any movesegmentalgear.

by any suitable means and is engaged by a spring ment imparted to thearm 63 by lever 62 will be transmitted to and will produce a similarmovement in arm 64.

It will be understood that the thickness of the parts used in theoperating mechanism is necessarily restricted to relatively narrowlimits inasmuch as it is desirable to keep the width of the compartmentformed by plates I6 and I 8 as small as possible. Therefore theinvention also includes a means for insuring against any possibility ofthe teeth of the intermeshing faces of arms 63 and 64 slipping out ofengagement with each other. This means comprises I projections 12 formedon each link 62 and so positioned as to overlie, on each side, theportion of the gear faces 69, 10 which are in engagement with eachother.

' This support on each side of the gear teeth eiectively insures againstany possibility of slippage or of the gears becoming misaligned.

Slots 14 are formed in plate I8 and are adapted to receive projectinglugs 15 formed on pan 16, which lug's rest upon the supporting arms 63,64. 'I'he slots serve as vertical guides for the pan and keep it inalignment as it is moved up and down in response to a raising orlowering movement oi' arms 63, 64. To provideagainst a possible bendingof arms 63 and 64, brackets 11 are mounted upon the inner surface ofplate I8 andl are spaced therefrom a distance just'suflicient to providefor the vertical movement of the arms 63, 64 but will effectivelyprevent any horizontal movement or bending of the arms, such as might becaused by a careless person in forcing the lugs 15 against the operatingarms in positioning the pan within the drawer.

The mechanism at the inner end of the drawer is substantially similar tothat at the outer end, with the exception of the operating pinion and'I'he shaft 58 extends into the rear wall of the drawer and consequentlyit is only necessary to provide a lever 8l pivoted to two operatinglinks A82 which in turn are pivoted to one of the inner pan supportingarms 83 and 84.

These arms are pivoted at 85. 86 to the inner plate 26 of the innerwall, which is similarly provided with depressions 81, 88 so that thepivot point will not extend into and interfere with the positioning ofthe pan. Links,82 are formed with projections 89 which overlie theintermeshing gear faces of arms 83 and 84 and perform the same functionas projections 12 at the outer end of the drawer. Reinforcing brackets9U are also positioned at the inner end and function in the same manneras do the brackets 11 at'the outer end. Slots 8| formed in plate 20provide for guidind the pan during its vertical movement.` 4

The operation of the pan elevating mechanism is as follows: In responseto ,a turning movement o f handle 50, the pinion 5I causes rotation of asegmental gear 58 which in turn imparts a rotational movement to theshaft 56. Levers 6I and 8|, xed to shaft 59 cause the movement o f theoperating links 62 and 82 respectively, which in turn cause the arms 63and 83 to rotate about pivot points 65 and 85 respectively. In responseto this movement, the arms 64 and 84 are likewise In the arrangementjust described, the single handle 50 serves two purposes. It provides aconvenient means for moving the drawer laterally of the oven and at thesame time it comprises the external means for vertically positioning thepan. It is of course obvious that these two functions are entirelydistinct and independent,l and therefore a modified form of theinvention is illustrated in Figs. 5 and 6 wherein separate handles and|0| are provided, the former being mounted upon the shaft 52 (not shown)and adapted to be rotated to vertically po'sition the pan, and thelatter being fixed to the front face of the stove and used for movingthe drawer laterally. The handle |00 is relatively small and theoperator therefore will normally not attempt to withdraw the drawer bygrasping this handle but will pull the drawer out by means of the largerhandle |0|.

Another modified construction has also been illustrated in Figs. 7 and 8wherein a dial |04 is mounted upon shaft 52 (not shown), while thelarger handle serves to move the drawer laterally of the oven. The twohandles are positioned relatively close together as shown so that whenit is desired to move the dial |04 to adjust the pan vertically, thehandle |05 may be used as a con-U venient rest for the hand so as tomake it easier to turn the dial with one or two ngers. Suitableindicating means such as a pointer |06 may be provided on the dial toindicate the position of the pan elevating mechanism. If desired, theface of the drawer may be calibrated in terms of the vertical positionof the pan, and thus it is possible to position the pan at any desiredheight, without openingthe drawer, by setting'the indicator on' the dialto the desired point on the scale.
